Persian Invasion also features two fully playable campaigns, based around a vast campaign map:

The first focuses on Greek Hegemony, allowing you to play as any one of seven Greek City-States in a quest for dominance over all of Greece and beyond. Although you begin the campaign in a shaky alliance with your Greek neighbors, due to the Persian threat, it is only a matter of time before all hell breaks loose in a fierce fight for control.

The second campaign better simulates the main focal point of this modification; that being the Greco-Persian Wars. In this campaign the seven Greek City-States are fully united in defiance of the Persians, allowing you to muster soldiers from all the cities right from the start.

Not only can you play as Greeks and the mighty Persian Empire, but in both campaigns you can play as any of the following factions - Celts, Illyrians, Scythians, Dahae, India, Gerrha, and last, but not least, the Kingdom of Macedonia.

Macedonia is also a major highlight of the modification, because it is the only faction that can experience a military reform. This allows you to transform the small Macedonian state into a powerhouse, perhaps one that could even challenge the great Persian Empire!

Yes, it has been quite a while since this mod was started - over 4 years in fact. Over those years, since PI was started, it has been abandoned, brought back to life, changed it's look, been abandoned again, brought back to life, released as a beta version then abandoned, and finally resurrected one last time to be released in full!

Take a look here at some earlier instances of Persian Invasion:

PI would have probably remained in it's beta state if it hadn't been for a mysterious modder named Lanjane who suddenly showed up and completed all of the unit cards, and did some other tweaking to boot. The most lacking part of the beta was the absence of unit cards, and, as any player of Rome - Total War knows; they are a simple, yet completely fundamental part of the game.

Some of Lanjane's unit cards:

And so, I finally forced myself to delve back into the files and fasten together these pieces to complete the project that had been haunting me for so long -

You'll find the complete edition available in the downloads section. Enjoy!

Hi, I am a huge fan of your mod, I played it before the new release and the glitches were terrible. The new version is awesome!

I was playing a campaign though and after I saved and quit the game, I attempted to open it the next day and the same wouldn't open, instead the game crashed. This has happened twice, and I do have autosave off. I am not sure what to do, is there anything to fix this?

Was it playing fine before or did it just start doing this when you installed the patch or something? If the latter, try deleting map.rwm from the pi/data/world/maps/base and pi/data/world/maps/campaign/greek folder.
